AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2000-17-03 for all Fokker Services B.V. Model F.28 Mark 0100 airplanes. AD 2000-17-Start Printed Page 7045403 required inspections of the nose landing gear (NLG) main fitting to detect cracking of the NLG main fitting subassembly, and corrective actions if necessary. This new AD retains the requirements of AD 2000-17-03, requires installing a new part number NLG unit that terminates the repetitive inspections, and adds airplanes to the applicability. This AD was prompted by a report of an NLG main fitting failure. We are issuing this AD to prevent cracking of the NLG main fitting, which could lead to collapse of the NLG during takeoff and landing, and possible injury to the flight crew and passengers.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2000-17-03, Amendment 39-11876 (65 FR 52298, August 29, 2000). AD 2000-17-03 applied to all Fokker Services B.V. Model F.28 Mark 0100 airplanes. The NPRM published in the Federal Register on February 28, 2014 (79 FR 11351). The NPRM proposed to continue to require a one-time visual inspection, and repetitive eddy current and dye penetrant inspections of the NLG main fitting to detect cracking of the NLG main fitting subassembly, and corrective actions if necessary. The NPRM also proposed to require installing a new part number NLG unit that would terminate the repetitive inspections, and adding airplanes to the applicability.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012-0002R1, dated March 30, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition on all Fokker Services B.V. Model F.28 Mark 0100 airplanes. The MCAI states:

In 1997, a report was received concerning a Fokker 100 (F28 Mark 0100) aeroplane, where during landing following nose wheel touch-down, the nose landing gear (NLG) broke off just below the pintle pins. Subsequent inspection by the affected operator of other aeroplanes in the fleet identified three more suspect NLG main fittings. Eddy current (EC) and/or dye penetrant inspections of these units later confirmed that cracks were present on the inner side of the downlock plunger support web. The total number of flight cycles (FC) accumulated by the cracked NLG main fittings at the time of detection were between 9,300 FC and 17,600 FC.

This condition, if not detected and corrected, could result in further incidents of NLG collapse, possibly resulting in damage to the aeroplane and/or injury to the occupants. To address this potential unsafe condition [Civil Aviation Authority —Netherlands] CAA-NL issued [an] AD * * * to require repetitive inspections of the NLG main fitting and, depending on findings, rework or replacement of the NLG main fitting.

Since [that Netherlands] AD * * * was issued, it was determined that replacement of a Messier-Dowty (M-D, formerly Dowty Rotol) Part Number (P/N) 201071001 or P/N 201071002 NLG with, respectively, a P/N 201071003 or P/N 201071004 (which have a so-called `heavy weight' main fitting installed) or, respectively, with a P/N 201456001 or P/N 201461001 (which are so-called `heavy weight' NLG units) cancels the need for repetitive inspection and/or rework. The `heavy weight' main fitting was originally developed for an increased weight version (101,000 lbs. maximum take-off weight) of the Fokker 100, as well as for the Fokker 70 (F28 Mark 0070), and introduced on the production line.

M-D issued Service Bulletin (SB) F100-32-94 and Fokker Services issued SBF100-32-119, which provide instructions to install the P/N 201071003 or P/N 201071004 NLG on aeroplanes in service. In addition, Fokker Services issued optional SBF100-32-149 to introduce the P/N 201456001 or P/N 201461001 NLG units on aeroplanes in service.

In January 2010, a second NLG main fitting failure occurred. The results of the investigation showed that the fracture started from small fatigue cracks in the affected area. Prompted by this new occurrence, combined with the NLG certification methodology (safe life principle), EASA has decided that the existing terminating action, installation of a P/N 201071003 or P/N 201071004 NLG should be made mandatory. Alternatively, a P/N 201456001 or P/N 201461001 NLG can be installed, which meets the same requirement.

For the reasons described above, EASA issued AD 2012-0002, retaining the requirements of [the Netherlands] AD * * *, which was superseded, and to require the replacement of all P/N 201071001 and P/N 201071002 NLG units with, respectively, P/N 201071003 and P/N 201071004 NLG units, or alternatively with, respectively, P/N 201456001 or P/N 201461001 NLG units.

Replacement of a NLG main fitting or of a NLG unit on an aeroplane constitutes terminating action for the repetitive inspections for that aeroplane.

EASA AD 2012-0002 also prohibits, after modification of an aeroplane, installation of a P/N 201071001 or P/N 201071002 NLG unit on that aeroplane.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 11351, February 28, 2014) or on the determination of the cost to the public.

“Contacting the Manufacturer” Paragraph in This AD

Since late 2006, we have included a standard paragraph titled “Airworthy Product” in all MCAI ADs in which the FAA develops an AD based on a foreign authority's AD.

The MCAI or referenced service information in an FAA AD often directs the owner/operator to contact the manufacturer for corrective actions, such as a repair. Briefly, the Airworthy Product paragraph allowed owners/operators to use corrective actions provided by the manufacturer if those actions were FAA-approved. In addition, the paragraph stated that any actions approved by the State of Design Authority (or its delegated agent) are considered to be FAA-approved.

In the NPRM (79 FR 11351, February 28, 2014), we proposed to prevent the use of repairs that were not specifically Start Printed Page 70455developed to correct the unsafe condition, by requiring that the repair approval provided by the State of Design Authority or its delegated agent specifically refer to this FAA AD. This change was intended to clarify the method of compliance and to provide operators with better visibility of repairs that are specifically developed and approved to correct the unsafe condition. In addition, we proposed to change the phrase “its delegated agent” to include a design approval holder (DAH) with State of Design Authority design organization approval (DOA), as applicable, to refer to a DAH authorized to approve required repairs for the proposed AD.

No comments were provided to the NPRM (79 FR 11351, February 28, 2014) about these proposed changes. However, a comment was provided for an NPRM having Directorate Identifier 2012-NM-101-AD (78 FR 78285, December 26, 2013). The commenter stated the following: “The proposed wording, being specific to repairs, eliminates the interpretation that Airbus messages are acceptable for approving minor deviations (corrective actions) needed during accomplishment of an AD mandated Airbus service bulletin.”

This comment has made the FAA aware that some operators have misunderstood or misinterpreted the Airworthy Product paragraph to allow the owner/operator to use messages provided by the manufacturer as approval of deviations during the accomplishment of an AD-mandated action. The Airworthy Product paragraph does not approve messages or other information provided by the manufacturer for deviations to the requirements of the AD-mandated actions. The Airworthy Product paragraph only addresses the requirement to contact the manufacturer for corrective actions for the identified unsafe condition and does not cover deviations from other AD requirements. However, deviations to AD-required actions are addressed in 14 CFR 39.17, and anyone may request the approval for an alternative method of compliance to the AD-required actions using the procedures found in 14 CFR 39.19.

To address this misunderstanding and misinterpretation of the Airworthy Product paragraph, we have changed the paragraph and retitled it “Contacting the Manufacturer.” This paragraph now clarifies that for any requirement in this AD to obtain corrective actions from a manufacturer, the actions must be accomplished using a method approved by the FAA, the European Aviation Safety Agency (EASA), or Fokker Services B.V.'s EASA Design Organization Approval (DOA).

The Contacting the Manufacturer paragraph also clarifies that, if approved by the DOA, the approval must include the DOA-authorized signature. The DOA signature indicates that the data and information contained in the document are EASA-approved, which is also FAA-approved. Messages and other information provided by the manufacturer that do not contain the DOA-authorized signature approval are not EASA-approved, unless EASA directly approves the manufacturer's message or other information.

This clarification does not remove flexibility previously afforded by the Airworthy Product paragraph. Consistent with long-standing FAA policy, such flexibility was never intended for required actions. This is also consistent with the recommendation of the Airworthiness Directive Implementation Aviation Rulemaking Committee to increase flexibility in complying with ADs by identifying those actions in manufacturers' service instructions that are “Required for Compliance” with ADs. We continue to work with manufacturers to implement this recommendation. But once we determine that an action is required, any deviation from the requirement must be approved as an alternative method of compliance.

Other commenters to the NPRM having Directorate Identifier 2012-NM-101-AD (78 FR 78285, December 26, 2013) pointed out that in many cases the foreign manufacturer's service bulletin and the foreign authority's MCAI might have been issued some time before the FAA AD. Therefore, the DOA might have provided U.S. operators with an approved repair, developed with full awareness of the unsafe condition, before the FAA AD is issued. Under these circumstances, to comply with the FAA AD, the operator would be required to go back to the manufacturer's DOA and obtain a new approval document, adding time and expense to the compliance process with no safety benefit.

Based on these comments, we removed the requirement that the DAH-provided repair specifically refer to this AD. Before adopting such a requirement, the FAA will coordinate with affected DAHs and verify they are prepared to implement means to ensure that their repair approvals consider the unsafe condition addressed in this AD. Any such requirements will be adopted through the normal AD rulemaking process, including notice-and-comment procedures, when appropriate.

We also have decided not to include a generic reference to either the “delegated agent” or “DAH with State of Design Authority design organization approval,” but instead we have provided the specific delegation approval granted by the State of Design Authority for the DAH.

Clarification of Language in Paragraph (m)(2) of This AD

In paragraph (m)(2) of the NPRM (79 FR 11351, February 28, 2014), we specified to contact certain aviation authorities “for instructions and follow those instructions.” As part of the change described previously regarding “Contacting the Manufacturer” language, this text has been revised in paragraph (m)(2) of this AD to specify doing a repair using a method approved by the FAA, EASA, or Fokker Services B.V.'s EASA DOA.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM (79 FR 11351, February 28, 2014) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 11351, February 28, 2014).

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

Costs of Compliance

We estimate that this AD affects 4 airplanes of U.S. registry.

The actions required by AD 2000-17-03, Amendment 39-11876 (65 FR 52298, August 29, 2000), and retained in this AD take about 2 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost $0 per product. Based on these figures, the estimated cost of the actions that were required by AD 2000-17-03 is $170 per product.

We also estimate that it will take about 8 work-hours per product to comply with the new basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $525,000 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $2,102,720, or $526,680 per product.

We have received no definitive data that would enable us to provide a cost Start Printed Page 70456estimate for the on-condition actions specified in this AD.

Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120-0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES-200.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. “Subtitle VII: Aviation Programs,” describes in more detail the scope of the Agency's authority.

We are issuing this rulemaking under the authority described in “Subtitle VII, Part A, Subpart III, Section 44701: General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

Regulatory Findings

We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify that this AD:

1. Is not a “significant regulatory action” under Executive Order 12866;

2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);

3. Will not affect intrastate aviation in Alaska; and

4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
